Does the country effect matter in the capital structure decisions of European firms? VENANZI Daniela Full Professor of Corporate Finance, Roma Tre University, Department of Economics daniela.venanzi@uniroma3.it (corresponding author) NACCARATO Alessia Assistant Professor of Statistics, Roma Tre University, Department of Economics alessia.naccarato@uniroma3.it ABATE Giorgio Ph.D.Student in Statistical methods for Economics and Management, Roma Tre University, Department of Economics giorgio.abate@uniroma3.it Abstract (This version: May 2014) Recent international financial research finds that a firm s capital structure is not only influenced by firmand industry-specific determinants, but also by country-specific factors. A brief review of the last decade s studies on the country effect identifies some areas of potential development in empirical testing. We empirically address some of these areas with regard to the following aspects: test design, statistical methodology, and set of determinants. Based on a sample of seven apparently similar European countries and more than 800,000 variously sized firms (from the BACH-ESD database) over a ten year period (2000-2009), and using a simultaneous equations model (SEM) never used before by any scholar in this field, we test the direct effects of country characteristics on leverage, as well as their mediating role on the effects of firm- and industry-specific determinants. The emerging empirical evidence highlights the relevance of many institutional, financial and macroeconomic country characteristics, confirms the better ability of banks in selecting, monitoring and financing small and risky firms, and shows that the demand-side perspective can better explain some counter-intuitive effects of some determinants on leverage.

1. Introduction The choice of capital structure is a hot issue in international financial research. Since the Modigliani-Miller (1958) seminal contribution, many theories have been formulated and many empirical studies implemented. However, ample space for further research still remains, since the empirical evidence does not always support the theoretical hypotheses on the determinants of financial leverage, and often stimulates the formulation and testing of new hypotheses. In this context, the country effect on financial leverage seems to be a good candidate for further analysis. Prior research (e.g., Rajan-Zingales, 1995; Demirguc-Kunt Maksimovic, 1999; Booth et al., 2001; Giannetti, 2003; Hall et al., 2004; Bancel-Mittoo, 2004; Antoniou et al., 2008; de Jong et al., 2008; Aggarwal-Kyaw, 2009; Alves- Ferreira, 2011; Kayo-Kimura, 2011; Fan et al., 2012) finds that a firm s capital structure is not only influenced by firm- and industry-specific determinants, but also by country-specific factors. It also evidences that many country characteristics, such as the macroeconomic context, the institutional framework and the financial system, affect a firm s capital structure. In addition, the most recent studies demonstrate that country-specific factors can affect corporate leverage not only directly, but also indirectly, i.e. through their impact on the effect of non-country determinants (especially, firm-specific variables). In this paper we briefly review some of the last decade s studies on country effect and identify some areas of potential development in empirical testing: we address some of these areas in building our empirical analysis, discussed in this paper. Therefore, in comparison with the previous studies on country effect, our empirical analysis presents the following original features: a) we use a set of countries which is generally assumed to be homogeneous, in terms of type of financial system (all bank-based) and institutional origin (all civil law countries). The objective is showing that these countries significantly differ in both financial and institutional characteristics, although they are generally considered homogeneous in the empirical studies that adopt a broader set of countries; therefore, the empirical evidence emerging from the studies that use general taxonomies in classifying country and explaining the variance of leverage, is likely to underestimate the country effect and tells only a part of the story; b) we use a large sample of firms, which variously differ in terms of size and industry, including small and nonlisted firms, whose financial decisions are more subject to the institutional and financial constraints imposed by their domestic markets (Giannetti, 2003), and therefore allows to better highlight the country effect, compared with studies whose samples just include large listed companies; c) we use a broad set of determinants, at firm, industry and country level, breaking down each level in an ample set of variables that try to catch the different aspects of each level s impact on firms leverage; d) we estimate an explanatory model of leverage that fits both the cross-sectional and the longitudinal variability of corporate leverage, and therefore avoids the use of average values of dependent and independent variables over time, as some studies do. Furthermore, we ask our explanatory model to be robust over a range of years that includes different phases of the economic cycle: from the small crisis of 2002-2003 to the deep recent crisis of 2008-2009, through the expansion of 2006-2007; e) we estimate the country s impact on the capital structure choices in terms of both direct and indirect effects, in a model whose parameters are simultaneously estimated, including those related to the firm- and industryspecific determinants. In fact, adopting a simultaneous equations model (SEM), a statistical methodology never used before in this research field, we measure in the same regression model the direct impact of country, industry and firm-specific determinants on corporate leverage in a multi-year framework, as well as the country s indirect effects; the latter are expressed in terms of fully or partially mediated effects of the country characteristics on the impact on leverage of the firm- and industry- specific determinants. In doing so, we avoid the potential bias that can derive from an approach (used in many previous studies on country effect) that adopts a double-step estimation of direct and indirect country effects; f) we explicitly take into account the Welch (2011) criticism on the measurement of firms indebtedness, excluding the non-financial liabilities, that are generally related to the specific firm s business and industry 3

characteristics, and are not influenced by the determinants of the capital structure choice, when it represents an explicit managerial decision for covering the firm s financial needs; in the European countries, these nonfinancial liabilities (for example the provisions arising from labor market contracts or specific regulations) can have a major weight on the total sources of funds, distorting the measurement of financial leverage, when included; g) we use a sample of only bank-based countries: this allows us to realistically measure the financial leverage, considering also the short term bank debt, which represents a very important portion of financial debt, since it often disguises medium-long term debt by means of the tacit renewal mechanism; in bank-based countries, where corporate bonds are very marginally used as a source of funds, considering only the medium-long term debt (as usually done in the international studies based on very large and variegate country samples) implies the omission of most financial liabilities: h) our sample includes observations at size-class level rather than at firm level. As Myers (1984) and Fisher- Heinkel-Zeckner (1989) claim, transaction costs can explain some temporary deviations of a firm from its optimal capital structure, within an acceptable range of non-adjustment. Therefore, the observed static leverage measures do not approximate the target leverage each year. After verifying the important homogeneity of leverage within each size-class, we assume that the size-class averages of the dependent variable can better approximate the yearly target leverage, rather than the values of the individual firms observations. Furthermore, especially for the small-size firms, the average leverage in their class better reduces the risk that the observed values of leverage could be biased by financial market/system constraints, and therefore not representative of the target levels chosen by the firms. The paper is organized as follows. Section 2 presents an overview of the most recent international literature on country effect, that allows to build a general framework of the country characteristics usually included in the explanatory model of leverage, and the theoretical rationale underlying their expected impact on capital structure choice. Furthermore, it highlights some areas of useful improvement of the test design, in terms of both sample and statistical methodology, in order to better measure the country effect. Section 3 describes data, research design, methodology and variables adopted in our empirical analysis, outlining the tested hypotheses and the structure of the final model. The results are presented in Section 4. Section 5 concludes the paper. 2. The country effect on the corporate debt-equity choice 2.1 An overview of the recent empirical literature Except for the pioneering study by Rajan-Zingales (1995), only in the last decade the international literature analyzed the role of countries as a determinant of firm leverage (Booth et al., 2001; Giannetti, 2003; Hall et al., 2004; Antoniou et al., 2008; de Jong et al., 2008; Aggarwal-Kyaw, 2009; Alves-Ferreira, 2011; Kayo-Kimura, 2011; Fan et al., 2012). The main recent studies adopt a causal determinants-leverage explanatory approach, using samples large and variegate in terms of countries considered, that differ for the development stage of the economy (developed and developing countries), type of financial systems (bank- and market-based), and institutional environments (common and civil law countries, and related law and order frameworks). The country determinants are generally associated with firm-specific determinants (very similar across studies), and more rarely with industry-specific variables (Giannetti 2003; Antoniou et al. 2008 and Kayo-Kimura 2011), often omitted or simply included as industry dummies (fixed industry effect), no matter which characteristics they differ for. The country effect is generally measured including many country characteristics (institutional framework, financial system and macroeconomic scenario) as regressors of the leverage. Only a few studies include in the empirical test the country dummies, omitting a more explicit characterization. Almost all studies (Aggarwal-Kyaw, 2009 and Fan et al., 2012 are exceptions) measure both the direct and the indirect country effect on leverage, the latter being the influence of country characteristics on the impact on leverage of the non-country determinants (especially the firm-specific variables). The actual difference among these studies consists in the way they identify and measure these two effects. 4

Both effects can be included in the explanatory model of leverage disaggregating the country impact in its components (the country key characteristics) or, on the contrary, measuring it in aggregate terms. The latter studies either include in the model country dummies or country fixed effects, or estimate country by country independent regressions, without interacting firm-specific determinants with country characteristics, and only ex post rationalizing the different parameter estimates across countries. In addition, the country impact on intercepts or slopes of the leverage explanatory models can be assumed constant or varying across countries. The various studies use panel data and estimate regression models in order to explain both the longitudinal and the cross-sectional variability of leverage, including the time fixed effects or time-invariant variables as substitutes (i.e. Aggarwal-Kyaw 2009), with the exception of a one year analysis (for example, Hall et al. 2004, and Giannetti 2003) or the use of average value of variables over the whole period considered (de Jong et al. 2008, and Kayo- Kimura 2011). Using ex ante the average over time of the dependent and independent variables reduces the variability of the observed phenomenon; on the contrary, using firm-year observations, we aim at estimating an explanatory model that averagely fits across years and firms. In the hierarchical multilevel analysis used in Kayo- Kimura s study, the time variability is absorbed at the first level, considering time as an explanatory level such as firm, industry and country levels, therefore assuming that the impact on leverage of the other determinants (country and industry-specific) is time-invariant. Many differences among studies also emerge in the measurement of the dependent variable. Market leverage is used when the samples include listed companies, either alone or together with the book measure ; when the samples include unlisted companies, the book leverage is measured. Hovakimian et al. (2001) find that the choice between book and market value does not influence the empirical results significantly. Bowman (1980) shows that the correlation between the book and market values of debt is very high. However, using the market value of equity in measuring leverage could introduce spurious correlations with determinants that include market value of firm, as for example the market to book ratio, often used as a proxy of growth, when managers choose debt equity ratio referring to book values. Furthermore, market leverage is subject to market volatility (Aggarwal-Kyaw 2009). As far as the composition of leverage is concerned, two aspects are important: firstly, the nature of debt included in measuring leverage: either a total indebtedness formulation (more frequently adopted), including financial and non-financial debt (i.e account payables and provisions for pensions or deferred expenses funds), or a financial leverage measure; secondly, the composition of the term structure: either only long-term debt (more frequently used)or long and short term debt separately or together, no matter what is the maturity. There is no universally used measure of leverage. As Welch (2011) highlights, most researchers probably spend little time pondering their measures, and simply copy what their predecessors have adopted. A total indebtedness approach assumes that both managers and current and potential lenders look at the total debt of a firm in order to evaluate its financial risk. But it should be said that the non-financial liabilities are generally related to the specific firm s business and industry characteristics, and are not explicitly influenced by the determinants of the capital structure choice; for example, the accounts payable largely depends on both the industry practices in paying suppliers, and the intensity and/or stability of the firm relationships with them (which are significant, for example, in lean production systems and in industrial districts), and the provisions arising from labor market contracts or specific regulations are influenced by the human capital intensity of production. Fan et al. (2012) consider only financial debt, but include in the denominator of the leverage ratio the total assets, therefore implicitly considering the non-financial debt as net worth: Welch (2011) largely demonstrates that this assumption is incorrect. Only Giannetti s (2003) financial leverage measure seems to be exempt from Welch s criticism. Analogously, the most used long term debt ratio fails to explain a large part of firms indebtedness, especially in bank-based countries, where the banks short term debt often disguises medium-long term debt, by means of the tacit renewal mechanism, which allows lenders to control entrepreneurs' opportunistic behavior threating them of not renewing the loans, and corporate bonds are very marginally used as a long term source of funds. However, it should be considered that the determinants of short term debt can partially differ from those of long term debt. In addition, it shouid be considered that the short term debt often serves as a first instance source of funds for 5

financing unexpected needs, and therefore could be inconsistent with the objective of explaining the target leverage, pursued by the firm in a long term horizon, because it is biased by contingent circumstances. Therefore, some smoothing mechanisms of contingent volatility should be used. 2.2 Relevant country characteristics While financing policies seem to have similar patterns of behavior around the world (i.e. the debt ratios seem to be affected in the same way and by the same type of variables), despite the evident institutional differences (Rajan and Zingales, 1995; Booth et al., 2001), many studies on country effect emphasize that country macroeconomic, financial and institutional factors may have an important influence on capital structure, and that these effects on leverage are both direct and indirect, which means that country variables both affect the leverage levels of firms and play a moderating role in the relationship between leverage and its firm-level (more often) and industry-level (more rarely) determinants. Giannetti (2003) points out that the across-country similarity of financing behavior emerging from some studies is apparent and seems to be due to the bias induced by their using samples of large listed companies: in fact, large listed companies have easier access to international financial markets and, for this reason, their corporate finance decisions are less influenced by institutional, financial and macroeconomic peculiarities of their domestic markets. We discuss in the following sections the most frequently used country variables and briefly review the reasoning supporting their impact on leverage. 2.2.1 Financial characteristics This set of variables mainly refers to the development stage of a country s financial system and concerns the availability of a wider spectrum of sources of funds at a lower cost. Banking system development and bond market development positively influence the firm s leverage: more borrowing options could be available and creditors could be more willing to lend at lower costs. Stock market development negatively influences the firm s leverage, because a broader supply of funds and a lower information asymmetry between managers and investors decrease the cost of equity, and therefore determine a higher managers propensity to issue equity to finance investments. However, the stock market turnover enhances creditors willingness to lend, thanks to better opportunities to monitor the listed firms, or makes banks funds more available to non-listed firms. Furthermore, we can consider the financial system structure as a determinant of leverage (de Jong et al., 2008; Kayo-Kimura, 2011), since the understanding of the implications of the traditions of capital market-oriented and bank-oriented economies on the capital structure decision is important because they have direct implications on the sources of funds available to the corporate sector (Antoniou et al. 2008). Two different perspectives are generally adopted. From a first standpoint, the type of financial system (i.e. market versus bank based) is related to the degree of ownership concentration of companies. Firms in market-based countries have a less concentrated ownership structure, while in bank-based countries the concentration is higher: assuming that, in an agency perspective, debt plays an important disciplinary role against managers opportunistic behavior (Jensen 1986), the firm s leverage is assumed to be higher in market-based countries. From a different standpoint, however, in bank-oriented countries, banks play a significant role in gathering the information and monitoring management; therefore, we expect better access to external borrowing and, thus, higher debt levels. Purda (2008) shows that firms in bank-based systems are perceived to pose less risk than similar firms located in market-oriented environments. This is explained by two main characteristics of bank-based systems: i) bank debts represent inside debt, in the sense that a firm s close and specialized relationship with its bankers allows for the exchange of non-public information: access to this information allows banks to carefully monitor firm s management and scrutinize its behavior to ensure that it acts in the best interest of investors; ii) a second potential risk-reducing feature of bank-oriented financial systems is that banks become aware of repayment problems at an earlier stage and therefore can informally renegotiate credit terms rather than relying on formal bankruptcy procedures. The more frequently indirect effects tested are the following: 1. the banking system development (or, simply, its orientation) mitigates the effect of bankruptcy costs on leverage, in terms of business risk, size, and tangibility; 6

2. the banking system development (or, simply, its orientation) mitigates the effect of agency costs on leverage, in terms of tangibility and growth; 3. the two mediation effects above can be performed by the bond market s development; 4. the stock market s development mitigates the effect of agency costs on leverage, in terms of tangibility and growth. Fan et al. (2012) more explicitly consider the capital suppliers perspective and preferences as determinants of the firm s capital structure choice, and include a set of supply-side variables in the leverage explanatory model, such as proxies of the supply of funds available to the various financial intermediaries like banks, pension funds and insurance companies. We should also point out that the expected sign of the impact of some determinants of leverage can be different, depending on the prevalence of the supply-side vs. the demand-side perspective. For example, the creditor s rights protection (discussed below) might positively affect leverage because lenders are likely to be more willing to supply financing, but, on the other hand, the impact can be negative if we assume a demand-side perspective: firms will be more reluctant to borrow, fearing higher distress costs. 2.2.2 Institutional characteristics All studies recognize the important role of the country s institutional characteristics in influencing corporate decisions on capital structure, although the impact of these variables, in general, is not so evident. These determinants derive from La Porta et al. (1998) approach, which assumes that the type of legal system (common versus civil law countries) affects both the content of the laws and the quality of their enforcement, and therefore the extent of legal protection of external investors. Since the conflicts of interest between corporate insiders (managers and/or majority shareholders) and external investors (minority shareholders and creditors) are important factors that influence the corporate financial structure, the extent to which contracts can be used to mitigate these incentive problems depends on the legal system and enforceability of these contracts. Countries based on common law would offer outside investors better protection than those based on civil law, resulting in a prevalence of outside equity vs. debt, and of longer vs. shorter debt. The type of legal system is generally broken into a set of institutional characteristics, such as creditors right protection, shareholders right protection (anti-director rights), quality of laws and regulations, and promptness of their enforcement. Better protection of creditors and better legal enforcement mitigate the agency costs of debt, increasing the use of debt and decreasing the negative impact of business risk and growth opportunities and the positive impact of tangibility on leverage. However, a negative impact on leverage can be explained (de Jong et al. 2008) considering that the creditors right protection implies that debt is more risky for firms, since firms are likely to be forced into bankruptcy in times of financial distress. Firms, therefore, try to limit borrowing as they become concerned with relatively stringent debt contracts that creditors may impose on them. In addition, a good protection of creditors rights helps to lengthen the debt maturity for firms with volatile returns (Giannetti, 2003): firms in sectors with highly volatile returns are more likely to default due to temporary illiquidity; longer debt maturities could help reducing inefficiencies in these sectors. Better protection of shareholders is likely to align the interests of the agent with those of the principal, reducing the agency benefits of debt and hence the firm s leverage. Conversely, when the agent-principal problem is less important, firms are likely to use more debt: the diversified shareholders interests in exploiting tax shield value prevails against the risk-reducing perspective of managers and majority shareholders (who face both systematic and specific risks). Shareholders protection mitigates the asset-substitution and underinvestment problems, and therefore lessens the negative impact of growth opportunities on leverage; however, for closely held companies, these problems are less relevant and majority shareholders, fearful of losing control, may prefer to use debt rather than equity and therefore ownership concentration should lead to high leverage for growing firms. The corruption index, defined as the abuse of public office for private gain (Fan et al. 2012), reflects the extent to which corruption is perceived to exist among public officials and politicians. In the context of the firm s capital structure choices, the indicator proxies for the threat of investors rights expropriation by managers or public officers. Debt is expected to be used relatively more than equity when the public sector is more corrupt, since it is easier to expropriate outside equity holders than debt holders. The enforcement of debt contracts, i.e. the number of days needed to 7

enforce the respect of a debt contract (Djankov et al. 2007), or the presence/absence of an explicit bankruptcy code that regulates the resolution of default, specifying and limiting the rights and claims of creditors and facilitating the reorganization of the ongoing business (Djankov et al. 2008; Fan et al. 2012), affect the firm s leverage: poorly defined bankruptcy procedures and longer period to enforce a debt contract reduce the lenders bargaining power against the borrowers, and therefore discourage the use of debt or make it more costly. 2.2.3 Macroeconomic characteristics These country variables are less frequently used than others, or used more often as control variables.. Among these variables, inflation rate and inflation rate volatility are the most widely used regressors of leverage. Investors would be less willing to lend if they are not sure about the real returns on their loans, i.e., if they face higher inflationary risk. On the other hand, if interest rates do not appropriately reflect the inflation rate, inflation can be associated with higher debt levels, since the real repayment value of debt declines with inflation. Inflation uncertainty increases the firm s business risk through volatility in the firm s selling prices, costs, and volume of sales; therefore, in a highly inflationary country with high inflation uncertainty, firms will experience high business risk and carry less debt in their capital structure. As stated by Demirguc-Kunt and Maksimovic (1999), annual growth rate in national GDP is an indicator of the financing needs of firms, that triggers a positive effect on the use of debt. Capital formation can affect corporate leverage both positively and negatively: the accumulation of more retained earnings induces less dependence on debt usage, assuming the POH perspective; however, it could also generate more financial needs and therefore a higher need to use external sources of funds, i.e. more debt. The tax system in general, and specifically the tax treatment of interest and dividend payments, has been recognized as an important factor influencing capital structure choices since the seminal work of Modigliani and Miller (1963). Some studies (Booth et al. 2001; Fan et al. 2012) include this determinant at the country level, rather than at the firm level. They use the country s statutory tax rate or the relative tax advantage of debt, considering both corporate and personal tax rates according to Miller s (1977) formulation, or, alternatively, the tax treatment of dividend, distinguishing between countries with dividend imputation or tax relief systems, on the one hand, and countries with classical tax systems, that double-tax corporate profits, on the other hand: in the latter, firms are expected to use more debt than in the former. 3 Research design, data and variables 3.1 Test design and data This paper differs from the international studies about the country effect on the capital structure choice in many aspects, discussed below. 1) Firstly, we use a relatively homogeneous set of countries, in terms of type of financial system all bankbased and institutional origin: all civil law countries, of French (Belgium, France, Italy, Spain and Portugal) or German derivation (Austria and Germany). The objective is to show that distinguishing countries along these general taxonomies is not appropriate for understanding and measuring the country effect on the corporate capital structure choice. As showed below, these countries differ in both the financial and the institutional variables in a statistically significant way, although they are generally considered homogeneous in the empirical studies where an ampler set of countries is adopted. Therefore, the empirical evidence emerging from the studies that use these general taxonomies as country determinants of leverage, underestimates the country effect and tells only a part of the story. Furthermore, considering only countries operating in the same monetary system (European Union) and therefore eliminating some differences in terms of economic and political scenario, contributes to focus the country effect measurement on the explanatory variables included in the regression model, limiting the risk that the effect of these macro-context differentials could distort the financial and institutional determinants impact, especially when a larger sample of countries is used and the possibility of controlling them is likely to be limited. 8

2) Secondly, we use a large sample of firms (about 800.000), over a ten year period (2000-2009). The core set of data derives from the Bank for the Accounts of Companies Harmonized (BACH) and the European Sectoral references Database (ESD) projects (BACH-ESD). Firms data are aggregated into three size-classes, defined in terms of turnover: class 1 includes firms with less than 10 million euros of revenues (small firms), class 2 includes those between 10 and 50 million of revenues (medium-sized firms), and class 3 includes those with more than 50 million euros of revenues (large firms). The firms belong to 23 industries of the secondary and tertiary sectors, following the NACE (Nomenclature statistique des activités économiques dans la Communauté européenne) classification: 15 manufacturing industries, 3 energy, water supply and construction industries, 3 wholesale and retail trade industries, and 2 service industries (transportation and accommodation, and food services). The objective is to build an explanatory model of capital structure, which could be tested on a diversified set of firms and include a large set of determinants. In fact, we use a broad set of determinants, at firm, industry and country level, breaking down each level in an ample set of variables that try to catch the different aspects of its impact on firms leverage; therefore, we limit the use of dummy variables that categorize countries or industries in ex ante defined categories or taxonomies (see Table 2 for the determinants and section 3.2.2 for explanations and comments). Furthermore, our explanatory model should be robust over a range of years that includes different phases of the economic cycle: from the small crisis of 2002-2003 to the deep recent crisis of 2008-2009, through the expansion of 2006-2007. Our sample also includes small and non-listed firms: this strengthens the model generalizability and the significance of the results: in many of the countries included in the sample, large listed firms just represent a minor share of their countries GDP and a small proportion of the existing firms. Tentatively, this allows to better highlight the country effect, that could be obscured by samples only made of listed firms: indeed, large listed companies have easier access to international financial markets and, for this reason, their corporate finance decisions are less subject to the institutional and financial constraints imposed by their domestic markets. In conclusion, we estimate an explanatory model of leverage that fits both the cross-sectional and the longitudinal variability of corporate leverage, and therefore avoids using average values of dependent and independent variables over time (as some studies do). Due to the open nature of the sample, the number of firms in each size-class or industry can vary over the years. The BACH-ESD dataset includes data only if the number of firms in each size-class is larger than 5. In order to strengthen the analysis, the extracted sample excludes all the cases that present serial missing values. Furthermore, in order to avoid biased results, we built a balanced pattern of data: the number of observations in the sample for each country, industry and year is the same. Therefore, all the industries and countries that showed serial missing data were excluded: The final sample includes 4,830 observations: 690 for each country, 210 for each industry, 483 for each year, and 1,610 for each size-class. 3) Thirdly, our sample includes observations at size-class level rather than at firm level. After verifying the relevant homogeneity of leverage within each size-class, the yearly size-class averages of the dependent variable can better approximate the target leverage than the values observed at the individual firms level. As Myers (1984) and Fisher-Heinkel-Zeckner (1989) claim, transaction costs can explain some temporary deviations of a firm from its optimal capital structure, within an acceptable range of non-adjustment. Therefore, the observed static leverage measures do not approximate the target leverage each year. Furthermore, an open sample over time (in which the sample firms change year by year), while does not permit to test a dynamic adjustment model toward target [the BACH-ESD database also provides data for sliding samples, but the evidence emerging from Leary-Roberts (2005), Lemmon et al. (2008), Flannery- Rangan (2006) and Hovakimian (2001 and 2004) shows that the target adjustment process is neither linear nor on a yearly basis], could allow a more robust measure of the target leverage at the size-class level, thanks to an ampler and varying sample. In addition, especially for the small size firms, the average leverage in their class better smoothes the risk that the observed values of leverage could be biased by financial market/system constraints and therefore be not representative of the target levels chosen by the firms. The relative homogeneity of the dependent variable (i.e. the financial leverage) within each size class is tested by measuring how much of the dispersion across firms of a certain country-industry-year combination is 9

attributable to the within size class variability. We use the interquartile coefficients for measuring variability 1, weighting them by the number of firms. We obtain an average value of 35% for four of the ratios used in calculating the financial leverage and an average value of 52% for the fifth ratio (long term debt on total assets ratio) and a median value of about 20%. This means that most part of variability of the financial leverage across firms, in each country-industry-year combination, depends on size. 4) Fourthly, we estimate the country s impact on the capital structure choice in terms of both direct and indirect effects in a model whose parameters are simultaneously estimated, including those related to the firm and industry-specific determinants. In fact, adopting a simultaneous equations model (SEM), a statistical methodology never used before in this research field, we simultaneously measure (i.e. in the same regression model) the direct impact of country, industry and firm specific determinants on corporate leverage in a multiyear framework, as well as the country s indirect effects: these are explicated as fully or partially mediated effects that the country characteristics play on the impact on leverage of the firm- and industry- specific determinants. In doing so, we prevent the potential bias that can derive from an approach (used in many studies) that adopts a double step estimation of direct and indirect country effects: this approach ex ante assumes that the country indirect effect exists and therefore estimates separate regressions by country (or by other predefined subsamples of countries), hence regressing in a second regression the coefficients of the firm and industry determinants on the country s characteristics. Giannetti (2003) and Kayo-Kimura (2011) use a similar approach, but they use a cross-sectional approach and interaction variables instead of fully or partially mediated effects (see section 3.3 below for methodological details). While there are several merits in comparing international data, as correctly noted by Rajan-Zingales (1995), comparisons of firm-level accounting data across countries are not exempt from limitations. However, the harmonization in accounting standards and practices pursued by the BACH-ESD dataset is likely to greatly guarantee the comparability of data, since this is considered its main objective and is implemented at an institutional level; in fact, the project involves the Central Banks of the participating countries and was developed in close co-operation with the European of Central Balance Sheet Data Offices. 3.2 The variables Table 1 summarizes the dependent and independent variables used in the empirical test (the latter are the most significant measures of leverage determinants, selected among a large set of tested proxies). We briefly discuss them in the following sections. 3.2.1 The dependent variable [Table 1 about here] According to Welch (2011), we measure leverage only referring to the interest-bearing debt, because we want to identify the variables that influence the explicit financing choice of a certain corporate capital structure. We include both short term and long term financial debt, because our sample includes bank-based countries, in which bank short term debt often disguises medium-long term debt, by means of the tacit renewal mechanism, and therefore heavily weights on total financial debt (D_MAT in Table 2 measures the incidence of bank short term loans on total bank loans). The measure adopted for estimating leverage is not neutral, as Table 2 clearly shows. In fact, although financial leverage and total leverage are strongly correlated, we can see that they importantly differ in terms of mean and degree of variability (total leverage is more stable than financial leverage) 2. Furthermore, the proportion of short term debt is very important (it ranges from one third in Belgium to about two thirds in Italy) and cannot be ignored in analyzing the capital structure choice of the European firms. However, the 1 The BACH-ESD database provides average, median, first and third quartiles for all the ratios. 2 Note that all the variances are underestimated, since they are calculated on aggregated data, i.e. size-class industry year combinations. 10

short term debt component is often omitted in order to avoid its excessive time variability, since it is more flexible and better suited in matching the unexpected changes of financial needs (Shyam-Sunder and Myers, 1999), and therefore used by firms more as a contingent reaction than as a deliberate capital structure choice. In our study, however, using the size-class average rather than the individual firm observation, we smooth this effect, while maintaining the stable component of short term debt: in other words, the size class mean leverage, being the firms similar within the class, is a better proxy of the target leverage, smoothing both the frictions in the adjustment process towards the target capital structure and the temporary deviations for satisfying unexpected financial needs. We use book leverage instead of market leverage because we use a larger sample, including not listed companies. Furthermore, both the Graham-Harvey s survey (2001) and the subsequent studies in the European contexts by Bancel-Mittoo (2004) and Brounen et al. (2004), report that managers focus on book values when setting the financial structure. 3.2.2 The independent variables [Table 2 about here] We organize the independent variables in three categories, referring to the three macro-determinants of financial leverage (firm, industry, and country), whose characteristics they approximate. As said above, we limited the use of dummies, preferring to breakdown country, industry and firm effects through their respective characteristics. We included the year dummies as time fixed effects: however, as discussed above, in our test design the effect of time is likely to be (at least partially) absorbed by the time-variant determinants considered in the analysis, that belong to the three categories. We prefer to avoid considering time as an independent explanatory determinant such as country- or industry- or firm- specific determinants (as for example in Kayo-Kimura 2011), but explicitly assuming and tentatively explaining the longitudinal pattern of the analyzed phenomenon. 3.2.2.1 Size class (firm) specific As discussed above, our observations are considered at size-class level instead of at firm s level. We include the most common firm-specific determinants considered in the international empirical literature on capital structure choices: we simply measure them as size-class averages, for each country-industry-year combination. As far as the firm-level determinants of leverage are concerned, three main theoretical approaches are relevant: the trade-off, the agency, and the pecking order hypotheses, the latter being based on both the Myers-Majluf (1984) information asymmetries theory and the Donaldson (1961 and 1984) managerial and stewardship approaches. These theories, born as developments of Modigliani and Miller s (1958) approach of a perfect market, suggest that, when we include in the analysis market imperfections, several firm characteristics may determine firm s leverage; these theories often propose the same firm determinants, but the expected effects on financial leverage and the related rationales might change, depending on the adopted theoretical lens. We therefore analyze six firm-level determinants of capital structure: profitability, risk, taxes, liquidity, tangibility, and size. There is no consensus among the various theories on the influence of profitability on capital structure. The pecking order theory suggests a hierarchy of preference in the choice of funding sources: external equity would be the last resort, debt would come in second, and retained earnings would be the first choice. According to the work of Myers (1984) and Myers and Majluf (1984), this financing preference order is defined by the level of information asymmetry. In this context, Fama and French (2002) suggest that in a simple pecking order model, holding the investment level fixed, leverage would correlate negatively with profitability. Debt will grow as investment needs are larger than retained earnings. Instead, following Donaldson s approach (1961 and 1984), the preference order depends on the objectives of survival and autonomy in financing core investments, as well as on the external control aversion of managers (in public companies) and majority owners (in closely held firms). The trade-off hypothesis, in turn, states a positive linkage, because low profitability may increase bankruptcy risk (Fama and French, 2002), thus forcing firms in such a position to reduce leverage. Besides, profitable firms should be more leveraged, as they would benefit from corporate debt tax shields (Frank and Goyal, 2003); furthermore, the agency theory assumes a positive relationship, due to the disciplinary role of debt (Jensen, 1986). In our paper, profitability is measured as return on assets (ROA). 11

In a static trade-off framework, the firm s capital structure moves towards targets that involve the trade-off between tax advantages and bankruptcy and distress costs (Giannetti 2003). In order to examine the influence of taxation on financial leverage (Myers 1977; Graham 1996 and 2000; Graham- Tucker 2006), we use the level of non-debt tax shields (NDTS measures the incidence of depreciation on net turnover). We expect a negative influence on debt (De Angelo-Masulis 1980; Fama-French 2002; Miguel-Pindado 2001; Venanzi 2003), although some studies, both theoretically (Dammon-Senbet 1988) and empirically (Titman- Wessels 1988; Bradley et al. 1984; MacKie-Mason 1990) highlight the income effect of more capital expenses in addition to the substitution effect, therefore assuming a positive relationship, when the first effect overtakes the second. We expect a negative impact on leverage of bankruptcy costs, and we use the following proxies: asset tangibility (TANG), measured as the ratio of tangible fixed assets to total assets; risk, measured at firm level as operating leverage, i.e. incidence of fixed costs on total costs (OPRISK). A higher tangibility of assets indicates lower risks for the lender and reduced direct costs of bankruptcy; a higher risk indicates higher volatility of operating income and higher probability of bankruptcy. From the lender s perspective, a higher variability of returns on sales across firms in a given industry represents a sign of higher potential risk in financing these firms. However, assets tangibility might absorb the effect of liquidity (i.e. proportion of current assets), to which it is negatively correlated, and that of non-debt tax shield, to which it is positively correlated (see below): in this case, the sign of the linkage could be negative. According to the agency framework (Jensen and Meckling 1976), conflicts between stockholders and bondholders arise from asset-substitution and underinvestment. In order to minimize these conflicts, firms with high fractions of tangible assets mitigate the lender s risk: since tangible assets can be used as collateral for a given debt, the borrower is forced to use the resources in a pre-determined project, thus reducing the incentive to assume high risks (Titman and Wessels, 1988). Adopting the agency perspective, we can expect a positive impact of risk on leverage (Myers 1977; Kim-Sorensen 1986): in presence of growth-induced agency problems, high operating variance may reduce the agency cost of debt, rather than increase it, when size and industry effects are controlled. Furthermore, in closely-held firms, owners-managers of more risky firms could be oriented to use more debt for sharing business risk with lenders, and signaling their firms quality, where lenders are willing to lend. Liquidity, measured as a proportion of accumulated cash and cash equivalents on total assets (LIQ2), serves as an internal source of funds and will be used firstly instead of debt: we assume it is negatively linked with leverage; however, we also assume that the ratio of current assets to total assets (LIQ1) positively influences financial leverage, since it measures the working capital weight on total invested capital, that is likely to be financed by short term debt. The firm s size is a very common determinant in capital structure studies: almost all studies assume a size influence on leverage; however, both the theoretical motivations and the expected sign of this linkage could vary, since size is assumed to be a proxy of various determinants. A negative effect of size on leverage is assumed when size proxies bankruptcy costs (higher in larger companies because of longer and more complex bankruptcy procedures) or in case of asymmetric information problems (smaller in larger companies, that would be able to issue new shares, without reducing their market value) (Rajan and Zingales, 1995). A positive relationship indicates the importance of diversification in reducing bankruptcy risk: larger firms may be more diversified (Titman and Wessels, 1988). The agency perspective assumes a positive relationship, since size proxies the agency costs and/or the benefits of equity and debt (Vos-Forlong 1996; Berger-Udell 1998). In smaller firms, the agency costs deriving from separation of ownership and control are smaller and therefore the disciplining role of debt is less valuable; on the contrary, the agency costs of debt would be larger, due to their information opacity and larger flexibility in risk-shifting. However, assuming a demand-side perspective, the risk aversion of a non-diversified owner (such as the owner of a small firm) might reduce risk-shifting behaviors, because he/she pays more attention to total risk than to its systematic component, and his/her utility much depends on non-monetary rewards, such as self-esteem, firm s survival, his/her own or family reputation, and so on. The international empirical literature confirms the complex effect of size on leverage: most empirical studies find a positive influence (Fiend-Lang 1988; Chung 1993; Hovakimian et al. 2001; Fama-French 2002; Frank-Goyal 2003; Mao 2003; Gaud et al. 2005; McKay-Phillips 2005; Flannery-Rangan 2006; Anotoniou et al. 2008), but some of 12

them evidence a negative one (Kester 1986; Barton-Gordon 1988; Titman-Wessels 1988; Johnson 1997) or no effect at all (Ferri-Jones 1979; Chung 1993; Kim-Sorensen 1986). We used size class dummies, assuming a non-linear relationship with financial leverage. The determinants above are included in the analysis both in absolute and in industry-relative terms, the latter being measured as ratios between the size-class value of the variable and the related industry average. By means of these industry-relative variables, we take into account the firm s position within its industry; previous studies (MacKay- Phillips 2005) provided evidence that the financial leverage variation arises more within industries rather than between industries: therefore, we assume that the firm-specific determinants affect leverage not only as absolute measures, but rather when compared to their industry average. It is important to note that all calculations are based on data of firms included in the BACH-ESD sample, which does not represent all the participants in a given industry. 3.2.2.2 Industry-specific Many studies on capital structure employ dummy variables to control the industry effect on leverage. We include in our model only the manufacturing dummy (MANUFACT), that distinguishes manufacturing firms from tertiary sector firms. In fact, we prefer to detail the time-variant characteristics of each industry, following the Kayo- Kimura s (2011) approach and previous studies in the strategy field (Simerly-Li, 2000; Ferri-Jones 1979; Dess- Beard 1984; MacKay-Phillips, 2005), that rationalize the industry characteristics influencing leverage. Specifically, we include munificence, dynamism, business risk, and firms concentration of an industry. Munificence is the environment s capacity to support a sustained growth. Industries with high munificence have abundant resources, low levels of competition and, as a consequence, we can suppose that companies operating in munificent industries tend to have high levels of profitability. If we extend the predictions regarding the impact of firms profitability on leverage to an aggregate industry, we cannot expect an a priori relationship between industry munificence and leverage. As we discussed earlier, in fact, the pecking order theory recognizes a negative relationship between profitability and leverage, whereas the tradeoff theory demonstrates a positive one. Therefore we try to test both signs of the relationship. We measure munificence by means of the average industry return on sales (%EBIT). Dynamism reflects the degree of instability or non-predictable change in a given industry (Boyd 1995). Therefore, we assume that firms operating in more dynamic and less predictable environments have lower levels of debt. We measure industry dynamism with the industry cross-sectional dispersion of ROS (BUSRISK), measured as interquartile distance, standardized by the median. Lastly, we consider the influence of industry concentration on firm leverage using the well-known Herfindahl Hirschman (HH) index. Previous studies do not show a univocal sign of the relationship between industry concentration and financial leverage. Some studies (MacKay-Phillips 2005; Lyandres 2001) show that firms in concentrated industries cluster around higher leverage levels, whereas firms in competitive industries carry less leverage and are more widely dispersed. On the contrary, Lipson (1993) predicts lower intra-industry dispersion but lower levels of leverage for concentrated industries. However, the degree of concentration also influences the realside variables and therefore leverage through them. Competitive industries exhibit greater risk levels and more dispersion in risk. Profitability and asset size are both higher for concentrated industries. These findings suggest that concentrated industries are collusive, exhibiting higher and more stable profitability and less dispersion in profitability than competitive industries (MacKay-Phillips 2005). Product-market competition is less aggressive when leading firms have high financial leverage (Phillips 1995; Kovenock-Phillips 1997). Therefore, the HH effect on leverage is uncertain, since it passes through size, profitability and risk effects. In this paper, the HH index is defined as the sum of the squares of market shares of the largest one hundred firms within a given industry. The market share of a firm is given by the ratio of its sales to the total sales in the industry. Again, it is important to note that all calculations are based on data of firms included in BACH-ESD sample, which does not represent all the participants in a given industry. 3.2.2.3 Country-specific 13

Following the empirical literature on the country effect on leverage, discussed in section 2 above, we detail the country effect including in the regression model time-invariant and time-variant country-specific determinants. Here we only describe the independent variables used in the empirical test, without repeating the theoretical rationales and the empirical evidence underlying them, previously discussed. As for the time-invariant characteristics, we follow the approach of La Porta et al. (1998). As discussed above, all studies recognize the important role of the institutional country s characteristics in influencing corporate decisions on capital structure. Therefore we measure the degree of protection of shareholders and creditors rights, as recently reviewed by Spamann (2009) and Djankov et al. (2007): SHARIGHTS and CREDRIGHTS, respectively. Analogously, we include the variables that measure the quality of laws and regulations and the promptness of their enforcement: since conflicts of interest between corporate insiders (managers and/or majority shareholders) and external investors (minority shareholders and creditors) are important factors that influence the corporate financial structure, the extent to which contracts can be used to mitigate these incentive problems depends on these variables. JUDIC measures the efficiency and integrity of the judicial system, LAW assesses the law and order tradition of a country, CORR (Fan et al. 2012) measures the degree of government corruption. We omit the country dummies, assuming that the time-invariant characteristics better represent country fixed effects. As for the time-variant characteristics, we measure the development of both the stock market and the bank system, as well as some macroeconomics aspects. We expect that the more developed and liquid is the equity market, the lower is the information asymmetry between investors and insiders (managers or majority shareholders) and the higher the firms propensity to issue equity to finance investments, lowering debt levels. We measure the stock market development considering both capitalization (STOCKCAP) and turnover (STOCKTURN) ratios, together with the size of stock exchange list (DLC and its log transformation LN_DLC). However, stock market s liquidity and size positively influence the borrowers transparency and therefore firms financial leverage. A country s orientation to banks as a source of finance affects a firm s capital structure choices (Demirguc-Kunt Maksimovic, 1999). In some countries, like Germany and Italy, banks do not just provide loans, but play a significant role in information gathering and monitoring. Therefore, a highly developed banking sector favors a better access to external borrowing and, thus, higher debt levels. We measure the banking sector development with the ratio of private credit to total bank credit (BANKPRIVCR). As discussed above, we omit the classification of countries based on general taxonomies such as civil versus common law countries or bank-based versus market-based financial systems. In fact, the countries included in our sample significantly differ from each other, although classified as civil law countries and bank-based systems. Table 3 reports the Kruskal-Wallis tests for both the institutional and financial characters of the seven countries considered in this study, while Table 4 shows their average values. We can see that the mix of both the institutional and financial characters is different among the seven countries, although some similarities exist among them for individual variables of the two groups. For example, as far as the institutional characters are concerned, Austria and Germany belong to the same German-origin civil law group, but significantly differ on some aspects, such as corruption degree, law and judicial order, while they show the same values for the degree of protection of shareholders and creditors rights. Many differences also emerge among the 5 countries classified as French-origin civil law countries. For example, the shareholders rights protection varies from a minimum of 2 (Belgium) to a maximum of 6 (Spain). Analogously, France and Italy show very distant degrees of corruption. More differences also emerge among countries as far as their financial characteristics are concerned. For example, Germany, Italy and Portugal show a similar stock capitalization as a percentage of their GDP, but the number of their listed companies significantly differs. Analogously, stock exchanges in the considered countries appear very different in terms of transaction volumes and consequent information asymmetry levels between investors and insiders. [Table 3 about here] Finally, as far as the macroeconomic characteristics are concerned, we include: the country economic growth (VAR_GDP) as proxy of the financing needs of firms (Demirguc-Kunt - Maksimovic 1999) at country level: a positive effect of this variable on financial leverage is expected; 14

inflation rate (INFL). From a supply-side perspective, in a highly inflationary country, investors will be less willing to lend, since they are not sure about the real returns on their loans; however, from a demand-side perspective, if interest rates do not adequately reflect the high inflation rate, inflation can be associated with higher debt levels because the real repayment value of debt declines with inflation. Inflation uncertainty increases the firm s business risk and will carry less debt in the capital structure; capital accumulation (CAPFORM) influences leverage both positively and negatively, depending on whether it refers to financial needs or retained earnings. Macroeconomic data are obtained from the World Bank and International Monetary Fund websites. We include for some variables the lagged values, in order to consider their delayed effects on leverage (the suffix _1 or _2 is added to the variable name to show the corresponding lagged values). 3.3 Hypotheses and methodology 3.3.1 The tested hypotheses [Table 4 about here] We summarize our tested hypotheses in Table 5, articulated by the main categories of determinants: firm-, industry (sector)- and country-specific (F, S and C hypotheses, respectively). We briefly discuss here the hypotheses regarding both the direct and indirect country effects, according to the theoretical and empirical framework outlined in section 2 above, while we refer to section 3.2 for the rationales underlying the hypotheses regarding firm- and industry- specific effects. However, we discuss here the indirect firm and industry effects, when they are mediated by country determinants. In formulating hypotheses, we use D and I to identify, respectively, the direct effect on financial leverage and the indirect one, i.e. the effect of an independent variable mediated by another variable. [Table 5 about here] In less developed stock markets there is less information about firms for many reasons such as market illiquidity, weaker regulations, and lower corporate governance standards. This implies more information asymmetries among investors and insiders, raising the cost of capital. For this reason, the stock market development, in terms of both size and liquidity, has a negative impact on financial leverage. However, we could assume a positive effect on financial leverage of both liquidity and size of stock exchanges, since the market liquidity and the size of stock exchange improve firms transparency from the lenders standpoint and this effect can be enhanced when the country s judicial and law framework is tight. C-Hypothesis D1: The stock market development has a negative direct effect on leverage. C-Hypothesis I1: The stock market s liquidity and size (in terms of number of listed firms) have a positive indirect effect on leverage, mediated by the law and judicial environment. The bank sector development positively influences leverage, since firms have more borrowing options, there are more competition among banks, lower costs of funding and higher bank efficiency on choosing borrowers, reducing the adverse selection. C-Hypothesis D2: The bank sector development has a positive direct effect on leverage. The bank market development may also mediate the effects on leverage of some industry characteristics. Specifically, we assume that it mediates the industry dynamism and the concentration effects on leverage. In addition to the expected direct effect (negative for the first factor and both negative and positive for the second), the indirect effect of these two characteristic, mediated by the bank sector development, should be positive. This because in a more developed bank system, banks are more efficient at monitoring, with larger portfolios and better alternatives for diversifying: in this context, a more dynamic industry may be perceived as an opportunity rather than a risk, and more credit will be lent. Analogously, the presence of a more developed bank sector mitigates the negative direct impact on leverage of more competitive industries versus more concentrated ones, lessening the perceived risk that competition induces. 15

S-Hypothesis I2: The industry dynamism, mediated by the bank sector development, has a positive indirect effect on leverage, i.e. the bank sector development mediates the negative effect of industry dynamism on leverage, reducing it. S-Hypothesis I3: The industry concentration, mediated by the bank sector development, has a negative indirect effect on leverage, i.e. the bank sector development mediates the positive effect of industry concentration on leverage, reducing it. The degree of protection of investors, both creditors and shareholders, influences the capital structure choices, as discussed before. When we assume a supply-side perspective, we can formulate the following hypotheses: C-Hypothesis D3_a: The creditors rights protection has a positive direct effect on leverage. C-Hypothesis D4_a: The shareholders rights protection has a negative direct effect on leverage. However, when we assume a demand-side perspective, better creditors rights protection means higher cost of distress and bankruptcy for the borrowers, that should be more severely punished if they do not fulfill their debt obligations. In this scenario, firms might ask for less debt, discouraged by higher actual default costs. Analogously, when the agent-principal problem is less important, firms might use more debt, since the diversified shareholders interests in benefiting from tax shields overtakes the risk-reducing perspective of managers/majority shareholders; in addition, as far as closely held companies are concerned, if investors are more protected, control aversion makes the majority shareholders prefer debt to equity. C-Hypothesis D3_b: The creditors rights protection has a negative direct effect on leverage. C-Hypothesis D4_b: The shareholders rights protection has a positive direct effect on leverage. When analyzing the protection of investors rights, it is important to consider the mediation effect of the judicial context, that can enforce a tighter or weaker protection by the law system. A better judicial system means faster sentences, impartial and independent judges, and lower lawsuit costs. Therefore, we assume a positive direct effect on leverage of this variable (quality of the judicial system), assuming the mandatory nature of debt contracts and the residual nature of shareholders claims. Furthermore, we assume that the quality of the judicial system moderates the degree of protection of investors rights (we call this actual investor shareholder or creditor protection), enhancing the related direct effects on leverage, discussed above. C-Hypothesis D5: The quality of the judicial system has a positive direct effect on leverage. C-Hypothesis I2: The quality of the judicial system enhances the direct effect of creditors rights protection on leverage, irrespective of the sign of the relationship. C-Hypothesis I3: The quality of the judicial system enforces the effect of shareholders rights protection on leverage, irrespective of the sign of the relationship. Moreover, we can expect a joint effect of these two mediating effects (JUDIC, on the one hand, and CREDRIGHTS and SHARIGHTS, on the other hand) on bank sector and stock market development, respectively. We formulate the following hypothesis, which holds in every scenario, irrespective of the sign of the relationship between investor rights protection and leverage, based on the assumed perspective: C-Hypothesis I4: Both the quality of the judicial system and the investors rights protection (creditors or shareholders ) jointly mediate the effect of the development of bank sector or stock market, respectively, on leverage. Similar considerations can be made about the corruption level of a country. Corruption increases the investors risk: however, since debt obligations are legally binding, it is easier to expropriate equity holders than debt holders, and therefore we expect that the corruption level positively affects leverage and lessens the shareholders rights protection, increasing its negative influence on leverage or, alternatively, reducing its positive influence. C-Hypothesis D6: Corruption has a positive direct effect on leverage. C-Hypothesis I5: Corruption lessens the direct effect of shareholders rights protection on leverage, enhancing its negative impact or, alternatively, reducing its positive impact. 16

The protection of creditors rights is likely to moderate the impact on leverage of some firm-specific determinants. Referring to the above discussion about the rationales of firm-specific determinants of leverage (see section 3.2.2.1), we assume that a higher creditors rights protection moderates the negative impact of operating risk and the positive effect of asset tangibility on financial leverage, reducing both of them. Therefore, when laws and their enforcement give a better protection to lenders, the bank system is likely to offer more credit to firms with poor collateral and volatile returns. F-Hypothesis I2: The operating risk, mediated by creditors rights protection, has a positive indirect effect on leverage, that partially compensates its negative direct impact. F-Hypothesis I3: The asset tangibility, mediated by creditors rights protection, has a negative indirect effect on leverage, that partially compensates its positive direct impact. Lastly, we hypothesize the effects of the macro-economic characteristics on leverage, according to the international theoretical and empirical background outlined above (see section 3.2.3), and also consider their mediated effects, briefly discussed as follows. When we consider the positive effect of capital formation on leverage, since it is assumed to proxy the firm s financial needs, we can assume that this effect could be mediated by the degree of shareholders protection, expecting an indirect mediated effect on leverage, since a higher shareholders protection favors the choice of equity vs. debt. C-Hypothesis I6: The capital formation, mediated by shareholders rights protection, has a negative indirect effect on leverage, that reduces its positive direct effect. The industry munificence can explain the firm s ability to convert the economic growth of a country into economic returns and therefore retained earnings. To control for this effect, we can hypothesize a mediating effect of industry munificence (i.e. the %EBIT variable) on the positive impact of economic growth on leverage: firms operating in growing and munificent economies need less external funds (i.e. debt) for financing their investments, since they rely on higher retained earnings. C-Hypothesis I7: Economic growth, mediated by industry munificence, has a negative indirect effect on leverage, that decreases its positive direct effect. 3.3.2 Methodology and model structure There are many econometric models proposed in the academic literature that investigate which determinants, with particular reference to the country effect, have an impact on the firms financial structure. These models present several common features, since they are almost exclusively based on the use of panel data models, both with fixed and random effects (Aggarwal-Kyaw, 2009; Alves-Ferreira, 2011; Giannetti, 2003; Fan et al., 2012). The common objective of these studies is normally that of identifying the direct effects of the firm s and its market/context s characteristics on its financial structure. Some more recent studies pursue the objective of estimating also possible indirect effects of these characteristics. In general, the financial structure of a company is affected by both its typical profile (firm specific) and that of its business (industry specific), as well as by the geographic region in which it operates (country specific). The way in which these variables show their impact on the firm s financial structure can take different forms: in particular, we can have a so-called direct effect, explained by a relationship of dependency between two variables, and a so-called indirect effect, described by a relationship of dependency among three or more variables. For example, if Y is the response variable, and X1 and X2 are two variables that affect Y, we can reasonably assume that X1, in addition to its impact on Y, could also affect X2 and, hence, again Y. In the first case, we say that the impact of X1 on Y is direct, while in the second case it is indirect. The use of models based on panel data does not allow the explicit identification of possible indirect effects among the analyzed variables, so that in many studies (Hall et al., 2004; Fan et al., 2012; Aggarwal-Kyaw, 2009) the indirect effect is not considered at all. Furthermore, these models force an a-priori choice between estimators with fixed versus random effects, exclusively based on the outcome of a test of hypotheses. Other methods suggested in the literature imply the estimate of the different effects (direct and indirect) with distinct models (de Jong et al., 2008; Giannetti, 2003), or with the inclusion of interaction variables, i.e. variables 17

obtained as a product of the variables assumed to be triggers of indirect effects (Alves-Ferreira, 2011; Antoniou et al., 2008). In the first case, we first estimate the direct effects, ignoring the others; however, if the latter are significant, their omission causes an incorrect specification of the model, producing biased estimates (Green, 2002). When we use the direct effects estimated with a first model, for estimating the indirect effects with a second model, the bias has an impact also on the estimates obtained in that second phase. Furthermore, if we estimate the country effect by using separate equations for each country or including country dummy variables in the same equation, we ignore the possible interaction among countries: a comparison among them is only feasible in terms of comparison of coefficients, separately estimated for each country. In this paper, instead, we suggest a model estimated on the basis of a unique sample in which countries are not identified through the inclusion of dummies and the country effect is measured estimating the coefficients of both the country variables observed in the various countries (direct effects) and the firm and industry variables, whose effect is mediated by the same country variables (indirect effects). In this way, the intrinsic characteristics of a single country are explicitly included in the model, so that it is possible to estimate a coefficient for each of them, taking into account the variability of some characteristics among countries. As far as the second type of methodology is concerned, using the product among variables as a proxy of the indirect effects, does not allow the identification of a possible endogeneity relationship among exogenous variables (Kline, 2011; Kaplan, 2004). As a matter of fact, if we include in the model as a regressor the variable X1*X2 for identifying the possible impact of X1 on Y through X2, we ignore the fact that the same X2 could be dependent on X1. In other terms, this is like ignoring possible causality relationships among regressors, that, as generally known (Hayashi, 2000), produces inconsistent estimates of the model s parameters. Another category of models is that of the hierarchical linear models (HLM), used for example by Kayo-Kimura (2011), whose choice is certainly appropriate, since it allows to take into account the multilevel nature of the determinants. As a matter of fact, these methodologies consider the ways in which the variables interact to produce the distribution of the observed frequencies; at the same time, allow the identification of possible indirect effects of the determinants, through the estimate of the so-called random coefficient models. In relation to this type of models, we should point out that the definition of levels, i.e. the criteria underlying the classification of the observations, is extremely important. For example, the use of time as a first aggregation level of the observed data (like in Kayo-Kimura, 2011) could lead to the consideration of cross-sectional subsets of observations, and therefore to the loss of the information related to the time variability of all the determinants involved in the model estimation in the subsequent aggregation levels. Our methodology is based on simultaneous equations systems (Greene, 2002), that allow the evaluation, within a single model, of the overall set of relationships among all the variables, through the estimate of the variance and co-variance matrix of the entire system of equations. Hence, the use of this methodology allows the control of both the direct and indirect effects (effect decomposition: Kline, 2011), as well as of the possible endogeneity relationships among regressors, leading to consistent estimates of the parameters. The estimated system can be classified as a so-called Mediational Model (Mathieu-Taylor, 2006), and is based on the analysis of causal sequences starting from the theoretical assumptions about the causeeffect relationships among the variables. This class of models allows the evaluation of the existence, intensity, and direction of the effects. As far as the time variability of the determinants is concerned, we avoided a time (year)- based aggregation of the observations in order to catch the effect of the time variability for all the three classes of determinants specified in the model. Our model implies the estimate of the parameters of 8 linear equations. The first one (1) is the equation of interest and explains the effects of the determinants on leverage (LEV), while equations (2) - (8) are estimated only to make explicit their mediating role in the model: they cannot be considered as explanatory of the left hand side variable, i.e. the coeffcients estimated in each of these equations are only used to obtain the indirect effects in equation (1). 18

In other words, the parameters of the equations from (2) to (8) should be interpreted from a path analysis perspective (Kline, 2011), in the sense that they are instrumental for showing the indirect effects on leverage of some of the variables considered. If, for example, we are interested in assessing the TANG s effect on LEV, we need to assess both its direct effect measured through the estimate of 21 in equation (1) and its indirect effect, mediated by CREDRIGHTS, in equation (7). In the second case, the effect will be measured multiplying the coefficients 27 and 31. The estimate of different equations for catching the indirect effects on LEV allows the identification of paths, i.e. the identification of the indirect effects that go through two or more mediating variables. For example, as far as the TANG s effect on LEV is concerned, in addition to the effect mediated by CREDRIGHTS, it is also necessary to consider what is being mediated by JUDIC. In this case, the effect of TANG on LEV will be obtained multiplying the coefficients 27, 65 and 51. Hence, the overall indirect effect of TANG on LEV could be expressed as follows (see Figure 1): * *. 27 31 27 65 * 51 [Figure 1 about here] It can be seen that the final structure of the tested model, described below, is the result of a broad testing process of all the hypotheses listed in section 3.3.1, together with the selection of the measured proxies for the various types of determinants, using, as a criterion, the significance of both the proxies and the hypothesized links. The following is the final structure of the model: LEV t i j h 1 d 11 21 31 11 11 BANKPRIVCR _1 @1 ROA 0 0 0 0 t i j h BUSRISK d t 0 j h CREDRIGHTS 21 11 0 0 0 h NDTS 21 t 0 0 h HH t i j h 41 t 0 j h 11 MANUFACT CORR 0 0 0 0 21 INFL t 0 0 h 0 0 0 h 1 TANG t i j h t i j h 51 21 LIQ1 31 JUDIC 0 0 0 h t i j h CAPFORM _1 LIQ2 t 0 0 h 41 31 t i j h (1) 51 LN _ DLC t 0 0 h OPRISK 41 t i j h STOCKTURN t 0 0 h ROA t i j h 2 2 BANKPRIVCR 3 4 t i j h 32 % EBITt 0 j h 12 t 0 0 h t i j h 3 13 NDTS BUSRISK % EBITt 0 j h 4 54 VAR _ GDP _ 2 t 0 0 JUDIC CORR 0 0 0 h 5 0 0 0 h t i j h t i j h 6 6 CREDRIGHTS 5 7 SHARIGHTS t i j h 0 0 0 h t i j h 0 0 0 h 8 76 t i j h 65 CREDRIGHTS SHARIGHTS 7 8 27 28 TANG 0 0 0 h t i j h t 0 j h h 0 0 0 h t i j h 57 75 23 HH t 0 j h SHARIGHTS OPRISK t i j h 0 0 0 h 35 LN CAPFORM _ 1t 0 0 h 48 STOCKTURN t 0 0 h _ DLCt00h (2) (3) (4) (5) (6) (7) (8) 19

where t is the time index, i the dimensional class, j the industry sector, and h the country; the indices coefficients identify, in order, the regressor and the equation in which it appears. It is therefore clear that measuring the indirect effects as a product of the interested explanatory variables (Alves- Ferreira, 2011; Antoniou et al., 2008) does not allow the identification of the variables causal links. The problem is even more relevant when we analyze the interactions among more than two variables, since the possible causeeffect relationships are obviously more complex. We selected the variables included in each equation thanks to the identification of all the significant paths among them, making sure that every single indirect effect of these variables on LEV would be considered. We firstly investigated the links related to the firm specific variables, and subsequently we formulated further hypotheses on the country and industry determinants effects. For each category of explanatory variables, we verified the nature of their possible effect on LEV. We can distinguish four different types of mediation of the effect: in a first case, the nature of the effect is direct, i.e. it is not mediated by other variables (direct effect) in a second case the effect is only indirect (indirect effect), i.e. there is just an effect mediated by one or more variables, but without any direct effect in a third case we have a partial mediation, in the sense that we have both a direct and an indirect effect finally, we have a full mediation when the exhaustive specification of all the indirect effects makes the previously identified direct effect insignificant. As said above, the 4 types of effects cannot be seen with the simple inclusion of interactions among variables in the model, since they prevent from identifying the directions of the causal relationships among the variables. The mediational models, thanks to their ability to assign a direction to the identified relationships, are therefore the most appropriate tool for hypothesis testing. The estimate of the unknown parameters of the system of equations was obtained with the maximum likelihood with complete information method: the estimates therefore are consistent, efficient and sufficient. In order to assess the model s fitting to the observed data, we used the usual and most popular indicators in the literature, with particular reference to the SEM models: 1. Akaike Information Criterion (AIC), a test of relative model fit. The preferred model is that with the lowest AIC value. = 2 2 ( ), where k is the number of parameters in the statistical model, and L is the maximized value of the likelihood of the model; 2. Root Mean Square Error of Approximation (RMSEA). RMSEA values smaller than 0.1 indicate a good fit. A RMSEA value of 0.1 or larger indicates a poor fit. 3. Comparative Fit Index (CFI). In examining baseline comparisons, the CFI largely depends on the average size of the correlations in the data. If the average correlation between variables is relatively low, the CFI will decrease as well. A CFI value of 0.90 or higher is desirable. 4 Results 4.1 The path model graph In this section we illustrate the main results of the analysis. As already said (see section 3.3), we use a simultaneous estimation approach, path analysis, to measure firm, industry and country effects on capital structure. Path analysis involves the analysis of sets of relationships among variables, so that independent variables in one equation become a dependent variable in another equation (Smith, 2004). Figure 2 shows the path structure of the tested model. In the complete model the correlations between variables were also estimated, but since we are interested on their causal relationships, and in order to facilitate the interpretation of the graphic model, all the correlations between variables (two-headed arrows) are not displayed, and only causal effects between variables are represented (oneheaded arrows). The rectangle in Figure 2 represents the observed variables, while the circles represent the residuals of each equation. All mediation variables become dependent variables when used as mediation terms 20

between two variables. In other words, if one-headed arrow is pointing towards a variable, the latter becomes a new dependent variable, which has as many independent variables as the arrows pointing towards it. For example SHARIGHTS is a dependent variable influenced by CAPFORM_1 and STOCKTURN_1, and in the meantime it influences CORR (see equations 6 and 8 in 3.3.2). It is easy to see that the structure is quite complex with several flows of information following different paths, but all converging to financial leverage. Table 6 presents the results of the model estimation, and Table 7 the information criteria used to evaluate the model fit. These tests are usually difficult to interpret in terms of quality of the model (poor or good fit), since they take absolute values; in order to overcome this difficulty, we compare the absolute values obtained from the estimation of the model with the test values corresponding to both the empty and the saturated model. The test values from an empty model (i.e the model which only includes the intercept) are often used as a lower threshold, because this model does not give any information about the relationships among variables; on the contrary, the saturated model explores all the possible relationships among variables (it includes both correlations and causal relationships). Table 7 shows that the three fit tests are closer to those of the saturated model compared to those of the empty model. As we said above (section 3.3.2), some thresholds for the CIF and RMSEA tests are widely used. Therefore, we can conclude that the estimated model provides a good representation of the linkages among the considered variables. 4.2 Industry and size/firm effects [Figure 2 about here] As far as the firm and industry direct effects on leverage are concerned, the results achieved in this study are consistent with those of the mainstream literature. Panel A of Table 6 shows a negative effect between leverage and profitability (ROA) (Giannetti, 2003; de Jong et al., 2008; Alves-Ferreira, 2011). This finding is consistent with the POH and asymmetry information theory (F- Hypothesis D1_b). Due to the information asymmetry between investor and management, external funds are more expensive than retained earnings; more profitable firms have less debt in their capital structure because they prefer to finance their new investments with internal funds, that are cheaper than the external ones. The ratio of current assets to total assets (LIQ1) has a positive effect on leverage: we assume that this ratio measures the proportion of working capital on the investment structure of the firm. Firms with larger current assets increase their short-term liabilities, that better match the investment maturity. On the other hand, liquidity measured as a ratio of cash and cash equivalents to total assets (LIQ2) negatively affects leverage, confirming what we found on the impact of ROA: firms with more funds available need less debt to finance their investments. These results are consistent with our hypotheses (F-Hypotheses D6 and D7). Conversely, tangibility (TANG) has a positive correlation with leverage, as hypothesized (F-Hypothesis D3). This is a widely shared result in the classical literature (Stultz-Johnson, 1985; Giannetti, 2003; de Jong et al., 2008; Aggarwal-Kyaw, 2009, Fan et al., 2012). In case of bankruptcy, tangible assets are more likely to maintain their market value than the intangible ones. Therefore, the risk of lending to firms with higher tangible assets is lower and, hence, lenders will demand a lower risk premium. Furthermore, a firm s opportunity to engage in asset substitution can be reduced by secured debt, which reduces the agency costs and hence the cost of borrowing. Asset tangibility improves the chances to obtain loans because lenders have a better opportunity to recover them in case of default (Jensen-Meckling, 1976). The present value of bankruptcy costs also depends on the firm s operational risk (OPRISK), that proxies the returns volatility and increases the probability of incurring in bankruptcy. For this reason, a negative effect on leverage is generally expected (F-Hypothesis D4), but we found instead a positive one. We can explain this evidence observing the financial-system orientation of our sample. The negative impact of operational risk on leverage especially holds for firms operating in market-based countries, characterized by more distance between lenders and borrowers. In bank-oriented countries, firms have closer ties with lenders, that reduce the actual cost of failure to service debt (Antoniou et al., 2008). Furthermore, when we consider closely held firms, we can expect that their risk aversion is higher, and therefore using more debt in their financial structure allows them to share the business risk with lenders. 21

[Tables 6 and 7 about here] The non-debt tax shield (NDTS) reduces earnings before interest and taxes, lowering the net advantage of the tax shield. Our results show a negative coefficient for this variable, consistent with our hypotheses (F-Hypothesis D2). Firms with higher depreciation rates do not need high debt levels to shield their earnings, and therefore tend to have less debt (hence the substitution effect prevails). The effect of the firm s size is studied using a dummy variable, that splits the sample into two groups: small size firms and medium-large firms (@1). The positive coefficient evidences that small size firms are more leveraged than medium and large ones. This means that the correlation between leverage and size is negative (Rajan-Zingales, 1995). More asymmetric information and smaller and volatile retained earnings in small firms tend to push their financial choices towards debt rather than equity. Furthermore, small firms are often more closely held or family owned and therefore more concerned about losing control (F-Hypothesis D8_b). In testing the model, we introduced the industry-relative firm s characteristics, but we did not find any of them statistically significant. Simultaneously including firm and industry determinants in the explanatory model is likely to absorb both the absolute and the industry-relative effect of the firm s characteristics. Panel B of Table 6 shows the results of the industry determinants on leverage. As already said, we used many proxies of the same determinant: since they are mutually correlated, just the proxy that better explains each determinant was selected by the model. In addition, the time-variant industry variables replace in this model the industry dummy variables, mainly used in the international literature. The first variable is the business risk (BUSRISK), that proxies the dynamism of an industry: we found a positive linkage of this variable with leverage, that contradicts the expected sign (S-Hypothesis D2). However, since BUSRISK measures the industry cross-sectional (i.e. among firms) dispersion of ROS, its positive impact on leverage could confirm the better ability of the bank system in selecting borrowers, compared to the equity market. From a different point of view, the perception of higher risk in dynamic sectors could make equity more expensive and orient firms towards debt. Munificence proxies do not have a statistically significant direct effect on leverage, but an indirect one, which will be discussed at the end of this section. The Herfindahl Hirshman (HH) index has a negative impact on leverage. Previous studies do not show a univocal sign of the relationship. However, the negative effect is consistent with the previously found evidence that small and risky firms tend to be more leveraged, since a competitive industry includes riskier and smaller firms than a concentrated one (S-Hypothesis D3_b). In order to control for fixed effects, a manufacturing dummy (MANUFACT) is included in the model. The coefficient is negative and statistically significant: it implies that firms in tertiary industries (in our sample, trade and services) are more leveraged than manufacturing firms (S-Hypothesis D4). Two indirect effects were found, concerning firm and industry determinants. Firstly, non-debt tax shield (NDTS), when mediated by profitability (ROA), shows a positive coefficient, confirming the existence of an income effect of NDTS (Dammon-Senbet, 1988) (F-Hypothesis I1). Higher depreciations derive from larger capital expenses (new investments), that generate higher profits. If a firm is profitable, the firm s actual tax charge increases, since it has higher taxable income. However, the substitution effect still prevails, since the total effect of NDTS on leverage is negative, but smaller than the stand-alone direct effect. Secondly, the industry s munificence (%EBIT) is fully-mediated by the firm s profitability (ROA) and negatively influences leverage: this means that, thanks to the industry s munificence, profitable firms can rely on larger retained earnings and therefore tend to have less debt (S-Hypothesis I1). The mediated effect obscures the direct effect of industry s munificence on leverage. Some indirect effects of firm and industry determinants are also found, mediated by country characteristics. We prefer to discuss them in the next section, after the direct country effects. 4.3 Direct and indirect country effects 22

We discuss here the effects of country determinants on leverage, both as direct determinants of leverage and as mediating variables of other determinants. Many models were tested. This step by step process provided two useful results. First, the adopted methodology highlighted the existence of indirect effects and the type of mediation (full or partial). Second, creating multiple intermediate models permitted to select the best one in terms of goodness of fit, i.e. the final model described in Figure 2. The selection process stopped when the model fit was hardly improvable. Panel C of Table 6 shows the statistically significant coefficients for country variables, even after controlling for a broad range of industry and firm determinants, already discussed above. The degree of stock market development should reduce the cost of equity and the asymmetry of information, pushing firm to rely more on equity, and lowering their leverage. Both liquidity (STOCKTURN_1) and size (LN_DLC) of the stock market show negative statistically significant coefficients, that confirm the hypothesis (C- Hypothesis D1). Furthermore, the impact of these country variables is mediated by the institutional protection given to the shareholders. The impact on leverage of the mediation between financial and institutional characteristics is statistically significant. The liquidity of the stock market goes through two double mediation paths: firstly, through shareholder rights protection (SHARIGHTS) and judicial effectiveness (JUDIC); secondly, through shareholder rights protection (SHARIGHTS) and corruption (CORR). The two indirect effects have a negative and positive influence on leverage, respectively, but the negative effect still prevails, amplifying the direct effect of STOCKTURN_1 (C-Hypothesis I3). The first combined mediation tries to catch the actual shareholder rights protection, which represents the combined effect generated by the shareholder right protection (stated by law) and the efficiency and efficacy of the institutional system, called to enforce this right protection. The second one is the result of the lessening effect of corruption on leverage, even accounting for a better shareholder rights protection, supporting our C-Hypothesis I5. The indirect effect of the stock market size (LN_DLC) on leverage, when mediated by the judicial quality, is positive (according to C-Hypothesis I1), lowering the negative total effect. This means that in countries with many listed firms and an effective judicial framework, lenders benefit from a better firms transparency and hence firms use more debt for financing. The effect of bank sector development (BANKPRIVCR_1) is positive, consistent with the international evidence (de Jong et al., 2008; Kayo-Kimura, 2011) and our C-Hypothesis D2. Furthermore, the bank sector development mediates two industry determinants, generating two indirect effects. The first mediation is between industry dynamism (BUSRISK) and leverage: the indirect effect is positive, which means that a more developed bank sector is more efficient in evaluating and monitoring the borrower s risk and therefore can increase its credit lines; S- Hypothesis I2 is confirmed: since the direct effect of BUSRISK on leverage is positive, the mediation effect enhances the overall positive effect. The second mediation effect is between industry concentration (HH) and leverage: the coefficient is positive, contrasting our hypothesis (C-Hypothesis I3). It should be noted that the total effect of concentration on leverage is negative, i.e. firms in concentrated industries are less leveraged than firms in competitive industries. What we observe is that firms in concentrated industries are more leveraged in countries where the bank sector is more developed than in countries where the bank sector is less developed: this evidence is consistent with the assumption that a more developed bank sector increases the chances of having access to bank credit. It is more difficult to explain the following emerging evidence: firms in competitive industries are less leveraged in countries where the bank sector is more developed than in countries where it is less developed; if we consider the positive impact of risk on financial leverage, found in this study, both at firm and industry level, we can explain this evidence in terms of signaling content of bank debt for risky firms. In countries where the bank sector is more developed, having access to bank credit is more widespread and therefore weakens as a guarantee of reputation for risky firms, i.e. firms operating in more competitive industries. The degree of creditor protection has a positive correlation with leverage, supporting the supply-side perspective (C-Hypothesis D3_a). Countries with higher creditor rights protection (CREDRIGHTS) have more leveraged firms. In addition, the effect of the actual creditor rights protection is positive, too: the quality of the judicial system (JUDIC) enhances the positive effect of the creditor protection, pushing lenders to give more credit thanks to the availability of better protection (C-Hypothesis I2). The direct effect of shareholder protection (SHARIGHTS) on 23

leverage is negative and significant (C-Hypothesis D4_a), but turned statistically insignificant when mediated by judicial system and level of corruption: this shows a full-mediation effect of these variables on leverage. As we see in Figure 2, the final model does not show a direct effect of shareholder rights protection on leverage, but only a negative indirect one (which confirms the C-Hypothesis I3): this means that the protection actually (rather than nominally) granted is the factor that better encourages firms to use equity for financing their needs. The indirect effect mediated by the level of corruption (CORR) is positive, confirming the C-Hypothesis I5. Higher levels of corruption tend to reduce the benefit of shareholder rights protection when using equity, switching the preference to financial debt. However, the overall indirect effect remains negative. The actual creditor rights protection, i.e. the indirect effect of CREDRIGHTS mediated by JUDIC, also influences two firm s determinants. As shown in Figure 2, this variable mediates the effects of asset tangibility (TANG) and operational risk (OPRISK), on the one hand, and financial leverage, on the other. The hypotheses (F-Hypotheses I2 and I3) formulated for this two indirect effects, assuming a supply-side perspective and the actual protection rather than the nominal one, are both rejected. The presence of a higher protection enhances the effect of providing tangible assets as collateral for increasing bank debt. This means that a demand-side perspective prevails: in countries where the creditor rights are more protected, the cost of debt for the borrowers is higher, due to higher distress and bankruptcy costs (lenders can more efficiently claim the enforcement of their credit contracts); therefore, the borrowers who can offer more tangible assets as collateral are more oriented to use debt, since they reduce these costs. As far as the operating risk is concerned, we obtain a negative mediating effect of creditor rights protection, that reduces the positive direct effect of firm s risk on leverage. Again, a demand-side perspective prevails: riskier firms tend to share the business risk with banks (the direct effect of OPRISK is positive), for various reasons, discussed above (see section 3.2.2.1). In countries where creditors are more protected, bankruptcy costs are higher and therefore this risk sharing is less convenient for borrowers. Moreover, the direct effects of both the quality of judicial system and the corruption level are positive, as expected (C-Hypotheses D5 and D6). Therefore, these countries institutional characteristics have an overall positive effect on leverage through both the direct and the mediating effects. The last part of Table 6 shows the coefficients of the statistically significant macroeconomic determinants. The 2- year average annual economic growth (VAR_GDP_2) is fully mediated, i.e. the direct effect on leverage becomes insignificant when mediated by industry munificence and firm s profitability: the indirect effect is negative, consistent with the POH perspective (C-Hypothesis I7). Inflation (INFL) has a negative direct effect on leverage, that confirms the supply-side viewpoint (C-Hypothesis D7_b). The negative coefficient of lagged capital formation (CAPFORM_1) qualifies it as a proxy of retained earnings; furthermore, this effect is enhanced when mediated by shareholder rights protection, generating a negative indirect effect. Hence, the total effect is boosted in countries where high shareholder rights protection reduces the information asymmetry, lessening the advantage of debt with respect to equity: this evidence supports the POH perspective, and our country hypotheses D9_b is confirmed. Finally, the year dummies did not show any statistically significant relationship with leverage: it is likely that the time fixed effects were better caught by macroeconomic and financial time-variant country s characteristics. 4.4 Robustness tests In this section, we check the robustness of our explanatory model on country effect, testing it with different subsamples, split based on size and time. In particular, we split the entire sample into two sub-samples based on size: a sub-sample of small firms (1.540 observations) and a sample of medium and large firms (3.080 observations); furthermore, we split the entire sample into two sub-samples based on time, in order to separate two different economic phases occurred during the period considered in the entire sample: a sub-sample refers to the small crisis period (2000-2004, with 2.310 observations), while the other sub-sample refers to the subsequent expansion period (2005-2007, with 1.386 observations). We decided to omit the last abnormal two years (2008-2009), characterized by the recent crisis. The objective is to test the general robustness of the explanatory model with different firms 24

sizes and economic phases. We verify the robustness of the model, comparing the signs and statistical significance of the determinants effects on financial leverage of each sub-sample to those previously found in the entire sample. The results are summarized in Table 8. For this test we use the standardized coefficients in order to correctly compare sub-samples that differ under various perspectives. The standardized coefficients, in fact, take into account the different variability of the parameters estimates and therefore allow a more accurate comparison of the sub-samples results. The evidence shows that most coefficients are statistically significant and their signs and values are similar to those of the entire sample. However, some differences emerge and can be explained, observing the different nature of the sub-samples. [Table 8 about here] Panel 1 shows the results related to the sub-samples based on size. We observe that for the small firms, due to their wider information asymmetries, the stock market represents a viable alternative for financing investments only in countries where the stock exchange is large (and therefore includes also the small companies); the liquidity of the stock market, instead, is not relevant for them. In fact, STOCKTURN_1 is not statistically significant in the small firms sample, but the standardized coefficient of LN_DLC is higher when compared to that of the entire sample; analogously, the opposite happens for the medium-large firms sample. The information asymmetry enhances the importance of collateral for small firms (TANG). Small firms with tangible assets can use more debt because the marginal reduction of the asymmetry is greater for them compared to larger firms, where the coefficient is less significant and negative. For the same reason, small firms in dynamic sectors (BUSRISK) could represent an exploitable opportunity for banks, that rely on a better selection and monitoring process of the small firm s performance compared to the stock market. Larger firms can rely on a better reputation and they may not need banks to soften their information asymmetry: this explains why the coefficient is not statistically significant for them. A larger coefficient of the ratio of current assets to total assets (LIQ1) is found on the small firms sample, which shows the importance of this determinant. Small firms are likely to be characterized by a larger proportion of current assets, since they operate more often in light industries that are less capital intensive and less sensitive to scale economies. Therefore, the relevance of current assets drives their financial needs, that are often financed by short term loans, in order to match the maturity structure. In the medium-large firms sample the effect of this determinant is much lower. The lagged capital formation s coefficient is smaller for the small firms than for the larger ones (CAPFORM_1). According to the rationale underlying this determinant discussed under 4.2, capital formation may have a lower impact on small firms because their ability to generate and maintain a stable retained earnings level is lower than in larger firms. Therefore, their potential retained earnings are a weaker substitute for financial debt. This result is also confirmed by the smaller negative coefficient of profitability (ROA) for small firms. Furthermore, the goodness of fit ratios are sufficiently acceptable in both sub-samples, with a CFI of 0,862 and 0,915 respectively for small and medium-large samples, compared to a 0,907 for the entire sample. As far as the indirect effects are concerned, values and signs of the coefficients in both sub-samples are quite similar to those of the entire sample. Panel 2 shows the regressions conducted on the sub-samples based on time periods. As already said, the aim is to isolate the small crisis period from the expansion one, in order to check if different economic conditions can influence the structure and the explanatory power of our model. The coefficient estimates seem to be robust for different economics phases. All the coefficients in both sub-samples are statistically significant (except for STOCKTURN_1 in the small crisis sample), with the same signs and similar values of the effects of determinants found in the entire sample. This can demonstrate that the significant economic effects are mostly captured by the time-variant country-specific determinants. The indirect country effects are consistent with entire sample, too. We also ran the model on sub-samples split based on a different discriminating criterion, suggested by an ANOVA test that clustered the following two periods: the initial period (2000-2001) and the remaining years (2002-2009). The results (omitted for brevity) are quite similar to those obtained in Panel 2. 25

5 Some conclusions This paper examines how country characteristics affect capital structure decisions in seven European countries, when size-class and industry specific characteristics are also considered in the explanatory model. The most important empirical findings emerging from the analysis are summarized as follows: the country s characteristics have an important impact on firm s leverage, both directly and indirectly, i.e. mediating the effects of firm and industry characteristics; among the country s determinants, those regarding the institutional framework are very influential. We note that the investor protection is important, but it is the actual protection that influences the capital structure choice, rather than the theoretical one, i.e. that ideally guaranteed by laws. In fact, the quality of the judicial system assures the effectiveness of the investor s protection, allowing for an effective and more rapid enforcement of contracts; the corruption level can vanish this protection, especially of shareholders rights, that are more easily expropriable. We find that the more protected the creditors, the more leveraged the firms; the more protected the shareholders, the less leveraged the firms. Both these findings support the sign expected from the supply-side perspective. However, if we consider the mediating effect of creditor protection on asset tangibility and risk in influencing financial leverage, a demand-side perspective prevails. In fact, in countries where creditors are more protected, the positive effect of asset tangibility on leverage is enhanced: a stronger protection of creditors triggers higher bankruptcy costs, that firms try to contain making use of collateral for guaranteeing their debt; riskier firms in countries where creditors are more protected and bankruptcy costs are higher use less debt, in order to reduce the probability of default; the financial system s characteristics of a country also affect the financial leverage. The more developed the bank system, the more leveraged the companies; the more developed the stock market, the less leveraged the firms. It is important to note that it is not the ratio of stock market capitalization to GDP that is relevant, but rather the liquidity of the stock market and the size of the stock exchange, i.e. the number of listed firms. The latter, however, has a positive indirect effect on leverage, that can be explained in terms of better firms transparency deriving from being listed; as far as the firm- and industry-specific determinants are concerned, our empirical findings importantly support the POH perspective. Firms profitability and industry s munificence and capital formation increase the retained earnings and therefore lessen the firms indebtedness. Analogously, both liquid assets availability and economic growth in munificent sectors decrease financial debt. Furthermore, firms are likely to aim at matching the maturity of sources and uses: larger current assets correspond to more debt (probably, short term); however, the tax implications of debt is an important determinant at firm level, and we find both the substitution and the income effect of non-debt tax shields; we see that small and riskier firms are more leveraged. The positive impact of risk on financial leverage was found at both firm and industry level (the latter measured as a cross-sectional dispersion of ROS among firms). Furthermore, these findings are supported by a negative linkage between industry concentration and financial leverage: more concentrated industries are likely to be characterized by larger firms and more stable competitive pattern among firms. This evidence proves: better selecting and monitoring skills of banks with respect to the equity market; the dispersion of profitability among firms and the potential return volatility (the operating leverage is an ex ante measure of operating risk) could represent in this scenario an opportunity rather than a threat for banks; furthermore, the opacity of small and risky firms makes debt less expensive than equity; the prevalence of the demand-side perspective: bank debt is likely to be used by risky firms for sharing risk with creditors and signaling business quality and firm reputation; furthermore, the risk aversion of closely held or entrepreneurial firms makes debt more attractive for financing; the macroeconomic characteristics of a country complete the country effect on capital structure choices: inflation reduces the use of debt, while economic growth and capital formation increases it. 26

Table 8 Robustness Tests The first column shows all the significant explanatory variables, split into firm, industry and country effects. Panel 1 shows the standardized coefficient of the whole sample. Panel 2 reports the direct (column 4-6) and indirect (column 5-7) effects for the small and medium-lerge size firms samples. Panel 3 reports the direct (column 8-10) and indirect (column 9-11) effects for the small crisis (2000-2004) and the subsequent expansion period (2005-2007) samples. Robust standard errors are given in parentheses. *,**,*** indicate that coefficients are significant at the 10%,5% and 1% levels, respectively.
